Nagarjuna Kristam	c451280883	PCI: tegra264: dma: Fix mis-matches with ICD ... Fix tegra_pcie_dma_stop() return type to bool instead of tegra_pcie_dma_status_t. Add NULL checks and atleast one DMA channel enable status in tegra_pcie_dma_initialize().

Jon Hunter	23e3912ef7	PCI: tegra264: Fix build issues using conftest ... The Tegra264 PCIe drivers don't build for kernels that don't have: 1. The structure mrq_pcie_request_req defined 2. The function pci_epc_deinit_notify() present This is currently being handling by building a dummy driver for kernels that don't have these. To simplify this, use conftest to detect if the above are present and modify the Tegra264 PCIe driver accordingly if they are not present. By using conftest we can remove the Makefile variable 'NV_OOT_PCIE_T264_SOC_SKIP_BUILD' and ccflag 'DNV_CONFIG_PCIE_TEGRA_DMA_DISABLE'. Finally, the PCIe drivers are always built as modules so simplify the Makefile and remove the usage of 'CONFIG_TEGRA_OOT_MODULE'.
